LLOYD SEESE, F NAVARRE, AND JAMES r. MQGUIRE, or MAssILLon, 01110.

J AMES' F. MCGUIRE, both citizens. of the United States, residing at Navarre, in the county of Stark and State of Ohio, and Massillon, in the countyof Stark and State of Ohio, respectively, have invented a new and useful Electrically-Controlled. Mocha nism, of which the'following is a specification.- y

Our invention relates to a block signal ar ranged to electrically control a mechanism carried in the engine cabywhich will automatically operate when a train runs into' a block without license, to apply the brakes on such train and clos'ethe engine throttle.

The object of our invention is to provide automatic means for stopping trains when passing a set danger'signal;

:Another object comprises means whereby the semaphore may be operated-electrically so as to either stop a trainor allow the train to pass thesemaphore, asdesired.

With these objects in view the invention consists'in the novel" construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it'being understood that various changes in the form,-proportions, size and minor details of construction may be made within the scope of the appended claims, without departing from the-spirit or sacrificing any of the advantages of the invention.

ings, the semaphore signals such as illustrated 1n Fig. 1- are located at the desired intervals along the railroad track, preferably at the entrance to each block. Within the hollow base 1 of each of the standards 2 upon which the semaphore is mounted, is 10- vcated a motor 3, upon the shaft of which is provided a gear 4, meshing with a gear 5 upon a shaft16, said shaft carrying a small pinion 7 which meshes with the gear 8, upon the shaft 9, said shaft being provided with a circuit breaker. For thepurposeofpreventing coasting or creeping ofthe motor a magnet brake 9 of anyusual type maybe appoint 18 whichis held in;engagement with the periphery of the disk 10 and a wire 19 connects the wire 17 with a contact point 20 which is diametrically opposite to the con tact point 18. The contact point 21, which is located adjacent the'switch 13, is connected by meansof' awire 22 with a contact vtion illustrated in the accompanying drawpoint 23 located around theperiphery of the disk '10 at a point halfway between the points 18 and 20; A contact point '24 is l)- cated diametrically opposite the point 23 and is connected by means of a wire 25 with a contact 26 adaptedto be engaged by the switch 13.

Pivoted at 27 upon the top of the shaft 2 is the usual semaphore signal provided with the red and white lights 28 and 29 respectively, and with the usual arm 30. A link 31 is pivotally' connected at 32 to the semaphore, the lower extremity of the link being connected to a wrist pin 33 carried upon the disk 34 which is mounted upon the shaft 9.

A finger 35 is'mounted upon the link 31 andlocatedintermediate the contact arms 36, to which arms is connected a wire 37 leading to a battery 38, said battery being connected by wires 39 and 10 to a white and a red tell taleli ght, respectively, said lights being located in the tower. A wire 41 connects the white light with a contact 4-2 and a wire 13 connects the red light with a contact let. Thus as the signal is brought into the danger position shown in Fig. 1, one of the contacts 36 engages the contact 14, closing the circuit through the red light in forming the operator in the tower that the signal is in the red position and when the signal is set in the clear position the circuit will be closed through the white light in the tower.

The arm 30 is provided with a rod 45 which is located downwardly at an angle to said arm as shown in the drawings and at the lower extremity of said rod is pivotally mounted at $6 a metallic comb 47 having a plurality of slightly flexible teeth 48, said comb being connected by a wire 49 with a battery 50 located within the housing 1, a wire 51 connecting said battery with the rail 52.

The cab A of the engine is provided with a supporting bracket 53, upon its roof, which carries a plurality of short rails or wires 54 adapted to contact with the comb teeth 48, when the signal is in the danger position, said rails 5% being connected by a wire 55 with a relay 56 carried within the cab. A wire 36 connects the relay 56 with the truck of the engine. The armature 57 of the relay is provided upon its extremity with a hook 58 which engages the catch 59 holding said catch in the position shown in Fig. 2. A spring 59 is attached to the catch 59 and arranged to pull said catch out of engagement with the hook 58 when the armature 57 is actuated by the relay 56. The catch 59 is provided with a finger 60, which contacts with a spring member 61 to which is connected one extremity of the coil of the solenoid 62. A similar spring member 63 is spaced from the member 61 and connected by a wire 64: with a battery 65, said battery being connected to the other extremity of the coil of the solenoid 62, the

wire 6st also connecting with one extremity of the solenoid 66, the other extremity of which is connected to the battery 65, a switch 67 being provided intermediate the battery and the solenoid 66.

The arniatures 68 and 69 of the solenoids 62 and 66 respectively are connected together and provided with an arm 70 which is pivotally connected to a lever 71 which operates the valve 72 of ordinary construction located in the air supply pipe 73 which is connected to the air reservoir 74. The air supply pipe 73 is connected with the open ended cylinder 75 within which is located a piston 7 6, the piston rod 77 thereof being connected to the lever 78, to which is attached the throttle rod 79. Located near the open extremity of the cylinder 75 is an outlet pipe 80 which connects with the open ended cylinder 81, a piston 82 being pro- 70 If it is necessary to stop a tram at the entrance to any particular block, the switch 13 in the tower is thrown into contact with the contact point 21, closing the circuit through the motor 3, thereby operating the 75 gear mechanism, bringing the signal into the position shown in Fig. 1 of the drawings. As the signal reaches this point the disk 10 will have rotated into a position, bringing the insulated strip 11, into contact with the points 18 and 23, thereby breaking the circuit and causing the motor to stop. As the train passes the semaphore, one or more of the short wires or rails 5-1, carried by the engine will contact with the 5 comb teeth l8 upon the semaphore arm, completing the circuit from the battery 50 to the relay 56, through the rail 52 and the wheels of the engine. As the relay 56 is thus energized, the armature 67 will be actuatedreleasing the catch 59 and allowing the spring 59 to draw the catch downwardly, bringing the contacts 61 and 63 together, completing the circuit from the battery 65 through the solenoid 62, operating the armature 68 which opens the valve 72, allowing air to pass from the reservoir 74 into the cylinder 75, operating the throttle rod which shuts off the engine. As the piston 76 moves near to the limit of its movement air will be allowed to pass from the pipe 73 through the cylinder 75, into the pipe 80, operating the piston in the cylinder 81, which operates the air valve 85, causing the air brake to be applied. When the block is clear, the operator in the tower closes the switch 13 upon the contact 26, completing the circuit from the bat tery 15, through the motor 3, through the contacts 20 and 2% operating the gear mechanism which moves the signal into the clear position. In this case the signal will rise up, bringing the comb teeth 48 out of the path of the short wires 54 upon the engine. The engineer must then get down from the cab and close the switch 67 before he can again start the engine. The closing of this switch energizes the solenoid 66 operating the armature 69 thereof, which closes the valve 72. The catch 58 must be set at this time opening the contact points 61 and 63, the same as before the coil 56 was energized. The throttle and air valve can then be operated as usual.
